It was just another late Friday night at Wichita State University — so late that it might have been early Saturday. Khondoker Usama, student body vice president, took a break from partying to go to a local Kwik Shop to get a snack and some gas. And it was there that he said he ran into a Donald Trump supporter with a chip on his shoulder.

Usama first noticed the man — white, in his 20s or 30s, motorcycle in tow — because the motorcyclist was berating a black man who Usama thought had asked for some gas money.

“The man was yelling at the African American guy, calling him a lazy ass, saying, ‘You guys don’t work,'” Usama told The Washington Post in a telephone interview. “He was using racial slurs.”

Then, the man turned his attention to Usama, a 23-year-old Muslim senior from Bangladesh, and his friend, a Hispanic male. He pulled his bike in front of Usama’s green Acura.
